mcedit is a powerful command-line tool that enables AI assistants to edit files and analyze projects through the Model Context Protocol (MCP). It provides a secure bridge between AI models and your local filesystem.

🎮 Demo

See mcedit in action with Claude Desktop:

• Reading and writing any text file
• Analyzing project structures
• Searching and modifying file content
• Creating and managing files and directories
• Applying suggested edits from AI models

Zed File Context Server

This extension provides a Model Context Server for file operations, for use with the Zed AI assistant.

It adds several slash commands to the Assistant Panel to help you work with files and analyze projects.

Configuration

To use the extension, you can optionally set a project directory in your Zed settings.json:

{
  "context_servers": {
    "file-context-server": {
      "settings": {
        "project_directory": "/path/to/your/project"
      }
    }
  }
}

If no project directory is specified, the current working directory will be used.

Integrating with Claude Desktop

To use mcedit with Claude Desktop:

1. If you haven't already, install mcedit:

cargo install mcedit

2. Find the path to your installed mcedit executable:

which mcedit

3. Add the following configuration to ~/Library/Application\ Support/Claude/claude_desktop_config.json:

{
    "mcpServers": {
        "mcedit": {
            "command": "/path/to/your/mcedit",  // Replace with the actual path from step 2
            "args": ["mcp"],
            "env": {
                "HOME": "/Users/yourusername",  // Replace with your username
                "PATH": "/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin",
                "PROJECT_DIR": "/path/to/your/project"  // Optional: specify your project directory
            }
        }
    }
}

4. Restart Claude Desktop and enable the mcedit tool.

5. mcedit will automatically create a sample README.md file in ~/project if no project exists, ensuring Claude can start working with files right away.

Logs and Troubleshooting

The mcedit server logs are available at:

~/Library/Logs/Claude/mcp-server-mcedit.log

Environment Variables

• PROJECT_DIR: Set this to specify your project directory. If not set, mcedit will use the directory provided by command line arguments, configuration files, or fall back to ~/project. You can also change the project directory at runtime using the change_directory tool.
• MCEDIT_LOG_LEVEL: Set to debug, info, warn, or error to control logging verbosity.

Security Considerations

When using mcedit, please be aware of the following security considerations:

• mcedit creates automatic backups before modifying files
• Path validation prevents access to files outside the specified project directory
• Review code changes suggested by AI before applying them
• Sensitive information in your files might be accessible to AI assistants
